VoIP and Unified Communications. Internet Telephony and the Future Voice Network

Translates technical jargon into practical business communications solutions This book takes readers from traditional voice, fax, video, and data services delivered via separate platforms to a single, unified platform delivering all of these services seamlessly via the Internet. With its clear, jargon-free explanations, the author enables all readers to better understand and assess the growing number of voice over Internet protocol (VoIP) and unified communications (UC) products and services that are available for businesses. VoIP and Unified Communications is based on the author's careful review and synthesis of more than 7,000 pages of published standards as well as a broad range of datasheets, websites, white papers, and webinars. It begins with an introduction to IP technology and then covers such topics as: Packet transmission and switching VoIP signaling and call processing How VoIP and UC are defining the future Interconnections with global services Network management for VoIP and UC This book features a complete chapter dedicated to cost analyses and payback calculations, enabling readers to accurately determine the short- and long-term financial impact of migrating to various VoIP and UC products and services. There's also a chapter detailing major IP systems hardware and software. Throughout the book, diagrams illustrate how various VoIP and UC components and systems work. In addition, the author highlights potential problems and threats to UC services, steering readers away from common pitfalls. Concise and to the point, this text enables readers—from novices to experienced engineers and technical managers—to understand how VoIP and UC really work so that everyone can confidently deal with network engineers, data center gurus, and top management.

Is the internet really transforming children and young people’s lives? Is the so-called ‘digital generation’ genuinely benefiting from exciting new opportunities? And, worryingly, facing new risks? This major new book by a leading researcher addresses these pressing questions. It deliberately avoids a techno-celebratory approach and, instead, interprets children’s everyday practices of internet use in relation to the complex and changing historical and cultural conditions of childhood in late modernity. Uniquely, Children and the Internet reveals the complex dynamic between online opportunities and online risks, exploring this in relation to much debated issues such as: Digital in/exclusion Learning and literacy Peer networking and privacy Civic participation Risk and harm Drawing on current theories of identity, development, education and participation, this book includes a refreshingly critical account of the challenging realities undermining the great expectations held out for the internet – from governments, teachers, parents and children themselves. It concludes with a forward-looking framework for policy and regulation designed to advance children’s rights to expression, connection and play online as well as offline.

Communications and Mobility is a unique, interdisciplinary look at mobility, territory, communication, and transport in the 21st century with extended case studies of three icons of this era: the mobile phone, the migrant, and the container box. Urges scholars in media and communication to return to broader conceptions of the field that include mobility of all kinds—information, people, and commodities Embraces perspectives from media studies, science and technology studies, sociology, media anthropology, and cultural geography Discusses ideas of virtual and embodied mobility, network geographies, de-territorialization, sedentarism, nomadology, connectivity, containment, and exclusion Integrates the often-neglected transport studies into contemporary communication studies and theories of globalization

If we had computers that knew everything there was to know about things—using data they gathered without any help from us—we would be able to track and count everything, and greatly reduce waste, loss, and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best. The Internet of Things has the potential to change the world, just as the Internet did. Maybe even more so. —Kevin Ashton, originator of the term, Internet of Things An examination of the concept and unimagined potential unleashed by the Internet of Things (IoT) with IPv6 and MIPv6 What is the Internet of Things? How can it help my organization? What is the cost of deploying such a system? What are the security implications? Building the Internet of Things with IPv6 and MIPv6: The Evolving World of M2M Communications answers these questions and many more. This essential book explains the concept and potential that the IoT presents, from mobile applications that allow home appliances to be programmed remotely, to solutions in manufacturing and energy conservation. It features a tutorial for implementing the IoT using IPv6 and Mobile IPv6 and offers complete chapter coverage that explains: What is the Internet of Things? Internet of Things definitions and frameworks Internet of Things application examples Fundamental IoT mechanisms and key technologies Evolving IoT standards Layer 1/2 connectivity: wireless technologies for the IoT Layer 3 connectivity: IPv6 technologies for the IoT IPv6 over low power WPAN (6lowpan) Easily accessible, applicable, and not overly technical, Building the Internet of Things with IPv6 and MIPv6 is an important resource for Internet and ISP providers, telecommunications companies, wireless providers, logistics professionals, and engineers in equipment development, as well as graduate students in computer science and computer engineering courses.

Invaluable guidance on the most important legal issues facing nonprofits today Internet communication is the lifeblood of countless nonprofit organizations, yet there exists no specific law to provide for its regulation. Without solid legal guidance, nonprofits risk not only missing out on the unlimited opportunities that the Internet has to offer, but also jeopardizing their tax-exempt status. The Nonprofits' Guide to Internet Communications Law analyzes and explains the laws applicable to Internet communications by nonprofit organizations. Nonprofit law expert Bruce Hopkins writes that with Congress and government agencies reluctant to create new law, it will ultimately be up to the courts to determine the future of Internet law affecting nonprofit organizations. Extrapolating from the underlying principles of existing law, Hopkins addresses the legal ramifications of Internet business activities, charitable-giving administration, fundraising programs, lobbying, political campaign activities, and more. The Nonprofits' Guide to Internet Communications Law proves an unparalleled resource for this emerging field.
